Early life
Vacherot was born in Roquebrune-Cap-Martin to parents Josse and Nadine Vacherot. He has three siblings. He holds dual French and Monégasque citizenship, having gone to school in and frequently visited Monaco; he therefore opted to represent them internationally in 2022.
Professional career
2022: First Challenger title
In 2022, Vacherot won his first Challenger title at the Nonthaburi Challenger, Thailand, beating Lý Hoàng Nam in the final. Vacherot became Monaco’s second Challenger champion and the first since Jean-René Lisnard in 2004.
2023: Masters debut
Vacherot received a wildcard for the 2023 Monte-Carlo Masters main draw, making his Masters debut. He lost in the first round to Luca Nardi.
2024: Grand Slam and top 110 debuts
Vacherot received a wildcard for the 2024 Monte-Carlo Masters, losing to ninth seed Grigor Dimitrov. Ranked No. 136, he qualified for the main draw at the 2024 Țiriac Open but lost his opening match to eventual champion Márton Fucsovics.
Vacherot reached the top 120 on 6 May 2024, following a semifinal appearance as a qualifier, at the 2024 Open Aix Provence., losing to eventual champion Alejandro Tabilo.
Vacherot made his Grand Slam debut at the 2024 French Open after qualifying, becoming the first player from the Monégasque Tennis Federation to qualify for the main draw. He lost in the first round to Alejandro Davidovich Fokina.
2025: Historic Masters title and top 30
Vacherot also received a wildcard for the 2025 Monte-Carlo Masters and recorded his first Masters win over Jan-Lennard Struff in straight sets. He became the first Monégasque player to win a main draw match at the tournament since Jean-René Lisnard in 2009.
In October, ranked No. 204, Vacherot won his first title at the 2025 Rolex Shanghai Masters as a qualifier, becoming the lowest ranked player to win a Masters 1000 tournament. After qualifying, he recorded his second and third Masters wins by defeating Laslo Djere in straight sets and then Alexander Bublik in the second round. Vacherot reached his first Masters 1000 fourth round following the retirement of 20th seed Tomáš Macháč. He then upset Tallon Griekspoor to reach his first Masters quarterfinal and thus became the lowest-ranked quarterfinalist in the event history in Shanghai, and the first player from Monaco to reach an ATP Tour and Masters-level quarterfinal at the same time. Next he defeated Holger Rune in the quarterfinals. Vacherot defeated Novak Djokovic in the semifinals, recording the first top 10 (and top 5) win for a Monégasque player in history, and becoming the lowest ranked player to reach a Masters 1000 final. In Vacherot’s 27th tour-level match, he defeated his cousin Arthur Rinderknech to win his first ATP Tour and Masters 1000 title. Going into the Shanghai final, Vacherot and Rinderknech had each won 3 matches after dropping the first set and collectively the cousins defeated 10 of the 32 seeds (5 each) in the draw.
Vacherot received a wildcard for the Swiss Open in Basel, but lost to Taylor Fritz, and he also received a wildcard for the Paris Masters and reached the quarterfinals. Vacherot reached a new career-high ranking in the top 30 on 3 November 2025.
2026: Major third round, top 15 and his second ATP title
In 2026, Vacherot continued his impressive ascent on the ATP Tour. He made his debut at the 2026 Australian Open, where he was seeded for the first time and recorded his first major match wins to reach the third round. In February, he reached the quarterfinals at the Dubai Tennis Championships, securing a victory over Ugo Humbert. In April, he made a standout Masters 1000 run by reaching the semifinals of the Monte-Carlo Masters as an unseeded player, with wins over Lorenzo Musetti, Hubert Hurkacz, and Alex de Minaur before falling to Carlos Alcaraz. He followed this by reaching the third round of the French Open and later reached the semifinals at the Japan Open in Tokyo, defeating Stefanos Tsitsipas and Arthur Fils. These strong results propelled him to a new career-high ranking of world No. 14 on 5 October 2026.
However, the late-season brought challenges, highlighted by a third-round defeat as the defending champion at the Shanghai Masters against Tommy Paul.
Vacherot quickly bounced back from this setback in November, winning the second ATP title of his career—and his first at the ATP 500 level—at the Swiss Indoors, where he defeated Jiří Lehečka 2–6, 6–3, 6–3 in the final after recovering from a set down. During his stellar title run in Basel, he secured consecutive victories over Rafael Jódar, Holger Rune, and Taylor Fritz.
